The volume of diagnostic data produced by WebLogic Server can be
adjusted to include more, or less, data. Note that the WLDF diagnostic
volume setting does not affect explicitly configured diagnostic modules.
By default, the diagnostics volume is set to Low.

To configure the WLDF
diagnostic volume:

In the left
pane, select Environment >
Servers.

In the
Servers table, click the name of the server
instance for which you want to configure the WLDF diagnostic
volume.

Select Configuration >
General.

On the Servers: Configuration: General page,
select one of the following values in Diagnostic
Volume:

Off — No diagnostic data is automatically produced.

Low — A minimal volume of diagnostic data is automatically
produced. This is the default.

Medium — Additional diagnostic data is automatically
generated beyond the amount that is generated for
Low.

High — Additional diagnostic data is automatically generated
beyond the amount that is generated for
Medium.
